Hello all,

I would like to replace the ignition coils and rear toe links as well as replace the spark plugs on my 02 S Type 3.0, pulled the code and I get a P0305 error - cylinder 5 misfire. I have already had the o-rings and o2 sensor replaced by the shop.

I noticed a how to guide for the toe links which is really informative and easy to follow.

I have not seen one out there while doing my research on the 3.0 coil replacement or spark plug replacement, which I know is much more difficult than on the V8. Is there any literature out there that could help walk me through it?

Also, since this is the first time I will be working on my Jag (and on any car in at least 10 years) are there any pointers or things I need to watch out for?

I have been scouring the forums and have found several already.

Thank you all in advance for your help.

 

DMD, you will have to pull the intake manifold off to get to the rear passenger sparkplugs and coils.

JTIS or www.alldatadiy.com (yearly subscribtion $25.00) will walk you right through.

If you are planning on keep the vehicle for awhile, you may want to replace ALL vacuum lines including the rubber elbow under the lower intake manifold (contact Nalley Jaguar in Atlanta for best prices don't forget to mention being a forum member to receive a 15% discount and free shipping when $75.00 or more is spent). <-- I believe the cost will come to around $130.00.

Some will say NOT to replace the upper and lower intake gaskets (seals) but FelPro makes good aftermarkets cheap! I would and have replaced them on 2 separate 3.0s.

The upper intake (plenum) is difficult the first time, but very doable by the DIYer. Figure on about 5 hours for all the above the first time around.

Don't forget to replace the yellow IMT Orings with the new green ones if not done yet!

Edit: One more thing, buy a set of FelPro valve cover gakets as well, better to have on hand when you remove the passenger rear spark plugs and you see oil down in the wells. If you don't simply return them for a refund! You will thank me later on this .

 

WOW! Thanks Joycesjag, this is very helpful. I also bought repair manual and cd from ebay in addition to subscribing to alldatadiy. Just ordered my parts from NalleyJaguar today and with the exception of the toe links (which I decided to buy later) everything came to under $400. I will get to work on this Next Saturday.

Now I gotta go get the oil, plugs, etc.

 

UPDATE:

Ok so here is what I plan on doing hopefully this weekend if everything gets delivered on time.

1. Coils
2. Spark Plugs - Bosh Iridium
3. Spark Plug Seals
4. Valve Cover Gaskets
5. Fuel Filter
6. Oil Filter - Mobile 1 High Mileage
7. Air Filter
8. Cabin Air Filter
9. Oil Mobile 1 Full Synthetic

I decided to hold off on replacing all of the vacuum lines and rear toe links (don't want to bite off more than I can chew my first time under this hood)

Is there anything I am missing or should be aware of?

Thanks in advance

 

(6) Upper intake gaskets (seals)
(2) Lower intake gaskets
(1) rubber elbow under the lower intake manifold
(2) IMT O Rings (green ones)

All 4 above should be replaced as long as the intake manifold is off

 

Replacing the gasket on the oil separator the lower breather elbow hose attaches to since they are prone to seepage.

@ joyceJag
I checked my maintenace logs on the car and the O rings were replaced in October . i just bought the other items you mentioned, but do you know the part number for the rubber elbow? I found this one on motorcars ltd - just couldnt find the part number on alldatadiy.com to validate

MANIFOLD TO INDUCT ELBOW SEAL
SKU: NCA3015BA

@NBCat - do you nkow the part number?

Thanks again all for your help.

 

DMD, That is NOT the correct part.

Motorcars Ltd: Crankcase Breather Elbow - XR845730

Jaguar Part# XR845730 is the lower rubber elbow just shy of $17.00 at most dealers.

The Lincoln LS uses the same elbow and their part number is 3W4Z-6767-CA, much cheaper than the Jaguar Dealer.

Here are a couple of links to help you out:

Any of those top hoses you will need to move are prone to break on occasion depending on when they might have been moved or changed last. Watch out for that coolant line on the top that splits off in two directions (I think you have that one on the 2002 but not sure). That is prone to breaking. Also when you take the manifold off, it might be a little dirty. Good time to give it a good cleaning on the inside of it. That elbow for me was a bear to get off and you might want to just do some cutting to get it out as was suggested by one of the senior members to me. Gus has some great help posts for all of this. An the stuff to put around all your threads of the plugs and bolts. Good luck.

 

Update:

What I thought was just a (fairly) simple fix, turned into a mammouth one. Check engine codes stated that my 5th cylinder was failing. once i removed the manifold and pulled out a coil.....NIGHTMARE!!!! there was so much oil covering the coils. The last mechanic to remove the manifold FORGOT to put the spark plug seal back on! There had to have been a half a quart of oil surrounding the three spark plugs! On top of that some of the bolts around the manifold were missing! THANK YOU ALL SO MUCH FOR TELLING ME TO ORDER THOSE EXTRA PARTS!!!! I needed every last one of them. I was under my hood for almost 11 hours trying to sort out what the JAGUAR mechanic did, that I didnt even get a chance to change my oil. Additinoally, I broke the upper radiator hose when i removed the manifold (@Amadauss - exactly what you predicted). So today I am going to replace that, do my oil change and cuss out a few people.

 

Hee hee I kinda had a feeling those valve cover gaskets would come in handy, but not fot that reason.

Wow 11 hours, but hey look at the knowledge you gained! Congrats on getting the job (almost) done.

Be sure to update us when 100% accomplished.

 

OMG. Nightmare.

Sad when DIY is so much better than the service, it just should not be like that. Good job you can DIY!

 

Right on!!!

Thats why I do what I do. (Does that make sense?)

 

I trust you will confront the mechanic who butchered your engine (assuming you owned the car when that work was done). You deserve major reparations for such shoddy work....

Congrats for doing the job right yourself. As John said, it is a shame when customers suffer both financially and operationally when so-called professionals hack up a repair job....

 

And not take the vehicle back to that shop again while spreading the word through all means possible so others don't have the same situation to deal with.

Update:

Miss Daisy is purring better than ever! I put the new hose on, took the manifold off again too make sure everything was in working order and then replaced the oil and what not. Thank you to MyBayAuto for letting me rent a bay out and helping me out along the way. If you are in the DFW area and want to diy, that's the place to do it.
I will let yall know asap who messed my car up.
